Can anyone tell me if it is normal for an ACK-450 ELT to have something
loose inside that rattles when gently shaken or just turned upside down?
The rattle is coming from under the circuit board and would require
unsoldering some components to investigate.

Just in case you think I'm totally nuts to ask this - the unit also had
a half inch long bare clipped off component lead that was laying on the
circuit board just waiting to short something out... This is the only
TSO'd part on my plane and it has also been certified (even though it
was new). These ELT's are a joke on so many levels.

I've messed with two of them and they both had the rattle and worked
fine FWIW. Maybe something with the g activator??
